MY SKELETON

Our body has a skeleton inside.

The skeleton supports our body

The skeleton is made of bones

Bones are

hard and rigid.

The skull is our head bone.

The ribs and

spine are in our

torso

MY MUSCLES

Bones and muscles help us move.

Muscles pull bones to move them.

Muscles are elastic and soft.

AND

NO

Muscles relax and contract.
